The Litmus will pack a 1-inch OLED screen, DNSe (“Dense”) 2.0 audio circuitry, and recordable hot keys so you can access the functions you use most often. Battery life is rated at 16 hours and the device handles MP3, WMA, and OGG files. FM radio, too. It’ll come in the three different colors shown above and in 2GB or 4GB capacities.

The Diamond’s main feature is audio upscaling, which “restores missing sound range,” according to Samsung. It’ll use DNSe 3.0 circuitry to offer what Samsung hopes to be the “World’s Best Sound Quality.” Other features include a 2.4-inch 320×240 screen, four hours of video playback (WMV, MPEG-4) and 30 hours of music playback (MP3, WMA, OGG, FLAC). The Diamond will ship in 4-, 8-, and 16-gigabyte capacities.
